Why I still write thank you notes by hand

My wife thinks I'm crazy but I sit down every Sunday and write thank you notes for gifts, dinners, help around the house. People remember it. Last week a guy I sent a note to three months prior brought it up and told me nobody does that anymore. That's exactly why you should. Takes 15 minutes and separates you from 90 percent of people out there. It's not hard, just intentional.
